Description

Technical Field

[0001] This utility model relates to the field of foundation pit support engineering technology, and in particular to a foundation pit inclined pile support construction device with real-time angle correction function. Background Technology

[0002] Traditional horizontal supports suffer from drawbacks such as large construction footprint, high carbon emissions, and non-recyclability. Inclined pile supports, as a novel form of support, offer advantages such as smaller construction footprint, higher construction efficiency, and recyclability, and are therefore increasingly being used. Through inclined steel lattice piles, they effectively resist lateral earth pressure and deformation within the foundation pit. However, during construction, the driving angle of inclined pile supports cannot be accurately controlled, leading to pile tilt deviations that affect support performance and fail to meet the design strength requirements of the support structure. Therefore, precise control of the driving angle of the inclined pile supports is crucial.

[0003] Currently, although certain technologies exist for pile correction, their application in inclined pile support construction for foundation pits is limited and unsuitable. Correction operations must be performed after the piles are driven in, which not only increases construction difficulty and cost but may also damage the piles, affecting their bearing capacity. Therefore, developing a technology that can monitor and adjust the pile angle in real time during inclined pile support construction is of great significance for improving construction accuracy and quality.

[0004] To address the aforementioned issues, there is an urgent need to propose a foundation pit tilt pile support construction device with real-time angle correction functionality. Utility Model Content

[0005] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a foundation pit inclined pile support construction device with real-time angle correction function. This device enables precise angle control during the inclined pile construction process, ensuring the accuracy of construction and the safety of foundation pit engineering.

[0006] This utility model is achieved by the following technical solution: a foundation pit inclined pile support construction device with real-time angle correction function, including an angle correction device and an inclined pile. The angle correction device includes an inclined pile moving track, an inclined pile limiting device, and a jack device. The jack device includes a top jack device and two lateral jack devices. The inclined pile limiting device is located at the bottom of the inclined pile moving track, the top jack device is located at the top of the inclined pile moving track, and the two lateral jack devices are symmetrically arranged on both sides of the middle end of the inclined pile moving track. The inclined pile limiting device has an inclined pile limiting channel. An angle monitoring device is installed inside the inclined pile. The angle monitoring device and the jack device are wirelessly connected to an external control system. During inclined pile construction, the lower end of the inclined pile is placed in the inclined pile limiting channel, the pile body is placed in the inclined pile moving track, and the pile body is driven in along the inclined pile moving track and the inclined pile limiting channel. The jack device controls the driving angle of the inclined pile.

[0007] Furthermore, both the top jack device and the side jack device are scissor jack devices. The scissor jack device includes a receiving seat, a scissor jack, and a support platform. The bottom of the scissor jack is installed in the receiving seat, and the support platform is fixed to the top of the scissor jack. The opening of the receiving seat of the top jack device faces upward, and the opening of the receiving seat is flush with the inclined pile moving track. In the initial state, the upper surface of the support platform of the scissor jack is flush with the inclined pile moving track. The opening of the receiving seat of the side jack device is located on the side and faces the direction of the inclined pile moving track.

[0008] Furthermore, the scissor jack includes a support assembly, a base, and an adjustment device. The adjustment device includes a screw and a controller. The lower end of the support assembly is fixed to the bottom of the inner cavity of the receiving seat through the base. The screw passes through the middle of the support assembly and is connected to the controller. The controller drives the screw to rotate, thereby controlling the support assembly to unfold or retract, so that the load-bearing platform rises or falls. The controller is wirelessly connected to an external control system.

[0009] Furthermore, the support assembly has a rhomboid structure and includes two upper support arms, two lower support arms, and two connecting shafts. The lower ends of the two lower support arms are hinged to the base, and the upper ends of the two upper support arms are hinged to the bottom of the support platform. The lower ends of the upper support arms and the upper ends of the lower support arms are respectively hinged to the corresponding connecting shafts. The screw passes through the two connecting shafts in sequence and is threadedly connected to the inner cavity of the connecting shafts. The rotation of the screw drives the two connecting shafts to move in opposite or relative directions along the screw.

[0010] Furthermore, the angle monitoring device includes two wireless inclinometers, which are symmetrically installed on both sides of the inclined pile. The wireless inclinometers are wirelessly connected to the control system to transmit the inclination of the inclined pile in real time during the construction process to the control system.

[0011] Furthermore, the receiving seat of the top jack device is welded and fixed to the top of the inclined pile moving track and is perpendicular to the plane of the inclined pile moving track.

[0012] The beneficial effects of this utility model are:

[0013] 1. The top jack device, two side jack devices, and angle monitoring device work together to detect and adjust the angle of the inclined pile. Through the coordinated work of the control system, the angle of the inclined pile can be accurately adjusted, improving the construction quality, ensuring that the inclined pile is driven in at the accurate angle, and effectively reducing the tilting deviation of the pile.

[0014] 2. The wireless inclinometer is wirelessly connected to the control system, transmitting the pile angle wirelessly to the control system. The control system automatically adjusts the jacking force of the scissor jacks based on the monitoring data, realizing dynamic control of the pile angle and ensuring construction accuracy.

[0015] 3. This device can correct the angle of the pile in real time, avoiding the complicated process of correcting the pile after it has been driven into the ground in conventional engineering projects. This reduces construction time and labor input, thereby shortening the construction cycle of the foundation pit project and reducing construction costs.

[0016] 4. The use of angle monitoring systems improves construction accuracy and efficiency, reduces material waste and rework, shortens the construction cycle, lowers overall construction costs, and improves the reliability and safety of foundation pit support, resulting in good economic benefits.

Detailed Implementation

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] Reference Figures 1-4 This invention provides a foundation pit inclined pile support construction device with real-time angle correction function, including an angle correction device and an inclined pile 1. The angle correction device includes an inclined pile moving track 2, an inclined pile limiting device 3, and a jack device. The jack device includes a top jack device 4 and two lateral jack devices 5. The inclined pile limiting device 3 is located at the bottom of the inclined pile moving track 2, the top jack device 4 is located at the top of the inclined pile moving track 2, and the two lateral jack devices 5 are symmetrically arranged on both sides of the middle end of the inclined pile moving track 2. The inclined pile limiting device 3 has an inclined pile limiting channel, the inner cavity of which is slightly larger than the inclined pile, ensuring that the inclined pile can be driven into the ground through the channel. An angle monitoring device 11 is installed inside the inclined pile 1, and the angle monitoring device 11 and the jack device are wirelessly connected to an external control system 6. During inclined pile construction, the lower end of the inclined pile is placed in the inclined pile limiting channel, the pile body is placed on the inclined pile moving track, and the pile body is driven in along the inclined pile moving track and the inclined pile limiting channel. The angle monitoring device transmits the angle information of the inclined pile to the control system in real time. The control system records and monitors the angle data. When the angle of the inclined pile deviates, the control system sends a command to the corresponding jack device based on the angle of deviation. The jack device then controls the driving angle of the inclined pile to adjust the pile angle in real time. The jack device, angle monitoring device, and control system work together to achieve precise adjustment of the pile angle, improve construction quality, ensure that the inclined pile is driven in at an accurate angle, effectively reduce the pile tilt deviation, and ensure that the allowable error of the penetration angle is no greater than ±1°.

[0025] Both the top jack device 4 and the side jack device 5 are scissor jack devices 7. Each scissor jack device includes a receiving seat 71, a scissor jack 72, and a support platform 73. The bottom 72 of the scissor jack is installed inside the receiving seat 71, and the support platform 73 is fixed to the top of the scissor jack 72. Specifically, the receiving seat of the top jack device is welded and fixed to the top of the inclined pile moving track 2, and is perpendicular to the upper plane of the inclined pile moving track. The opening of the receiving seat of the top jack device faces upwards, and the opening of the receiving seat is flush with the inclined pile moving track. In normal conditions, the upper surface of the support platform 73 of the top scissor jack 4 is flush with the inclined pile moving track 2. When the control system monitors the tilt angle of the inclined pile relative to the ground and needs adjustment, it transmits a command to the controller of the top jack device to raise or lower the top jack device 4. The receiving seat opening of the side jack device is located on the side and faces the direction of the inclined pile moving track. The receiving seat of the side jack device 5 is welded and fixed to the side of the inclined pile moving track. In normal conditions, the load-bearing platform of the lateral jack device 5 is flush with its receiving seat; when a command is received from the control system, the lateral jack device on one side needs to be adjusted to move towards the inclined pile until the inclined pile reaches the preset angle range.

[0026] The scissor jack 72 includes a support assembly 721, a base 722, and an adjustment device. The adjustment device includes a screw 723 and a controller 724, which is wirelessly connected to an external control system. The lower end of the support assembly 721 is fixed to the bottom of the inner cavity of the receiving seat 71 via the base 722. The load-bearing platform 73 is fixed to the upper end of the support assembly. The screw 723 passes through the middle of the support assembly. One end of the screw 723 is connected to the controller 724 (drive motor or hydraulic motor), and the other end of the screw 723 is rotatably connected to the side wall of the receiving seat. The controller 724 drives the screw to rotate, thereby controlling the expansion or contraction of the support assembly 721, so that the load-bearing platform 73 rises or falls, for applying loads to the inclined piles, thereby adjusting the angle of the inclined piles. Specifically, the support assembly 721 has a rhomboid structure and includes two upper support arms 7211, two lower support arms 7212, and two connecting shafts 7213. The lower ends of the two lower support arms 7212 are hinged to the base 722, and the upper ends of the two upper support arms 7211 are hinged to the bottom of the support platform 73. The lower ends of the upper support arms 7211 and the upper ends of the lower support arms 7212 are respectively hinged to the corresponding connecting shafts 7213. The screw passes through the two connecting shafts 7213 in sequence and is threadedly connected to the inner cavity of the connecting shafts 7213. The rotation of the screw 723 drives the two connecting shafts 7213 to move in opposite or relative directions along the screw, so that the support assembly 721 is in an unfolded or retracted state.

[0027] The angle monitoring device 11 includes two wireless inclinometers, which are symmetrically installed on both sides of the inclined pile 1. The wireless inclinometers are wirelessly connected to the control system to monitor the angle changes during the construction of the inclined pile in real time and transmit them to the control system. The control system monitors the tilt angle of the inclined pile in real time during construction.

[0028] The inclined pile moving track 2 includes two support rods 21 and multiple crossbars 22. The crossbars 22 are evenly distributed between the two support rods. The receiving seats of two lateral jack devices 5 are respectively welded to their corresponding support rods 21. The side spacing between the two lateral jack devices 5 is slightly larger than the width of the crossbars 22 to ensure the passage of the inclined pile. The top jack device 4 is welded to the top of the two support rods 12. The crossbars are preferably rotatably connected to the support rods to reduce resistance when driving the inclined pile in.

[0029] The specific steps for using the above-mentioned foundation pit inclined pile support construction device with real-time angle correction function are as follows:

[0030] S1: Before the commencement of the foundation pit project, prepare the necessary materials and equipment according to the design requirements and geological conditions. This includes pre-positioning the inclined piles for the wireless inclinometer 11, cement, sand, and gravel, as well as equipment such as the pile driver, inclined pile placement device, and wireless receiving platform. Simultaneously, level and clean the construction site to ensure the construction environment meets the requirements.

[0031] S2: Based on the design drawings and construction plan of the foundation pit, accurately mark the pile positions of the inclined supports at the construction site. Using surveying instruments such as total stations and levels, determine the specific location of each pile according to the designed angle and pile spacing, and mark it to provide accurate positioning for subsequent pile driving construction.

[0032] S3: Move the pile driver and angle correction device to the designated pile position. The angle correction device is installed on the support structure 8 or the support structure. Adjust the piling machine's stride and mast angle to make the main mast of the piling machine coaxial with the horizontal line of the pile position, ensuring the stability and accuracy of the piling machine and ensuring that the position of the inclined support steel pipe of the foundation pit is accurate and controlled within the allowable error range.

[0033] S4: Install the first inclined pile and drill rod, then use the pile driver's own crane to lift it onto the angle correction device, connect the drill rod to the drilling rig, and fix the inclined pile 1. If an angle deviation occurs, the control system 6 will automatically control the scissor jack device through the controller to correct the pile angle. The allowable error of the soil penetration angle is no more than ±1°.

[0034] S5: During pile driving, the angle monitoring system (including a wireless inclinometer and control system) is activated to monitor changes in pile angle in real time. The wireless inclinometer 11 transmits the monitored data to the control system 6 in a timely manner. The control system 6, based on the preset angle range and adjustment parameters, automatically controls the top jack device 4 or the side jack device 5 via the controller 724 to correct the pile angle. Construction personnel should closely monitor the monitoring data and adjustment process to ensure that the pile angle always meets the design requirements.

[0035] S6: After completing the driving of one inclined pile, proceed with the construction of the other piles in sequence according to the above steps. During the excavation of the foundation pit, continue to monitor the angle of the constructed inclined piles, observe their deformation and stability under actual stress, and take timely measures to deal with any abnormalities to ensure the safety and stability of the foundation pit project.

[0036] S7: After the piling is completed, remove each device in sequence.
